==How to use==
<span style="color:red">'''Note:'''</span>
<span style="color:red">The new version is mainly an upgrade for the 4B version. If your motherboard is pi 3B+/3B, please try to use the version before 2.6, it will be more stable. </span>
<span style="color:red">Only support VOLUMIO and Raspbian now, and you need use the last customized volumio version form us. </span>
=== <span style="color:blue">How to Play the Lossless Music by customized Volumio from us?</span> ===
Please download the last customized volumio from here: https://sourceforge.net/projects/u-geek/files/HIFI/, Download the img file which we provided, unzip and burn it into the micro sd card.
Insert the card to Raspberry Pi, connect the Raspberry pi to network.
Manage the sound card by web page.
'''Setting:'''
Set the I2S DAC to "On";
Select "Aoide DAC II" as the Output device;
Select "Aoide DAC II" as the DAC Modle;
Save and reboot.
PS:
Try to select '''R-PIDAC''' in '''volumio3'''
You can refer to the following picture.

Q1: Why My DAC card shows ALSA fault?
A:
1. This is a compatibility issue of VOLUMIO system. and we fund some related issues about ALSA on VOLUMIO.ORG.
Here also is anything we search on google: https://cse.google.com/cse?cx=partner-pub-0839303782430158:6119498809&q=ALSA%20&oq=ALSA%20&gs_l=partner-generic.12...1677.1677.0.2228.0.0.0.0.0.0.0.0..0.0.gsnos%2Cn%3D13...0.46j2116j2...1.34.partner-generic..0.0.0.
2. We recommend not to open the alsa option, otherwise it will result in the loss of the driver (configuration) file. in fact, this audio board supports hardware to adjust the volume. If the system fixes this problem, we will post a message on the wiki, please pay attention to our wiki.
